The scanner does not work. · Ensure that you place the document to be scanned face down
from the document feeder glass, or face up in the ADF.
· There may not be enough available memory to hold the
document you want to scan. Try the Prescan function to see if
that works. Try lowering the scan resolution rate.
· Check that the USB cable is connected properly.
· Ensure that the USB cable is not defective. Switch the cable
with a known good cable. If necessary, replace the cable.
· Check that the scanner is configured correctly. Check the
application you want to use to make certain that the scanner
job is being sent to the correct port.
The unit scans very slowly. · Check if the multifunction printer is printing received data.
Scan the document after the current job is completed.
· Graphics are scanned more slowly than text.
· Communication speed becomes slow in scan mode because of
the large amount of memory required to analyze and
reproduce the scanned image.
